The Weldability of Heat-Resisting Alloys (N-102)

Abstract

Study was made of the welding characteristics of heat-resisting alloys employed in turbosuperchargers, jet engines, and gas turbine wheels. Welds in five wrought alloys and two cast materials were subjected to the bead-on-plate test, restrained butt-joint test, and a special wheel-and-bucket type of test. Three types of cracking found to be prevalent were weld metal cracking, heat-affected-zone cracking, and cracks propagating from interbucket junctions. In general, Hastalloy "B" and Timkan 16-25-6 alloys appeared to be the least susceptible to welding defects.
